Overview

The SI2302 is a MOSFET made by IDCHIP in a SOT-23 package with 3 pins. -55℃~+150℃ 1.2V 10nC@4.5V 115mΩ@2.5V 120pF 2.3A 20V 300pF 350mW 80pF N-Channel SOT-23 MOSFETs ROHS.

PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NMOS_1G_2S_3D, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2848196).

Questions

Is there a KiCad symbol and footprint for the SI2302?

Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2S_3D and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SI2302?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the SI2302 datasheet?

IDCHIP publishes it: the Datasheet link on this page opens it.

Where can I order the SI2302?

JLCPCB lists it as part C2848196, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SI2302?

Parts like it in the library: the AO3400 by GOODWORK, the AP2300 by ALLPOWER, the SI2302-2.3A-JSM by JSMSEMI and the SI2301-A1SHB by JSMSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
